The actor and comic will re-team with Peep Show co-star Robert Webb for the series, which follows the lives and loves of the British Embassy team in Tazbekistan.

"It's such a good subject," Mitchell told Reader's Digest. "We couldn't believe that something along these lines hadn't been written before."

Mitchell will play Keith Davis, the newly appointed British Ambassador of Tazbekistan, while Webb is cast as Neil Tilly, Deputy Head of Mission.

"Like a lot of things we do, it's exploring different attitudes to authority," Mitchell explained. "In contrast to Peep Show, these are highly capable senior people who very much have jobs. But they have very different views on [how to do them]."

He added: "Some people will think my character is right and some people will think he's wrong, and both sets of people will be correct."

Our Men is expected to air in 2013, while Peep Show will return to Channel 4 on November 9.
